    摘要: A thermal processing operation is performed for a silicon wafer W (silicon single-crystal layer) in an atmosphere gas which is formed by a hydrogen gas or an inert gas or a mixture gas of these gases at a temperature in a range of 600° C. to 950° C. (here, the temperature should not be greater than 950° C.). By doing this, a quality of a surface of the silicon single-crystal layer is improved.

    摘要: This silicon wafer production process has a step of cutting a silicon wafer from a silicon single crystal ingot in a perfect region which includes a perfect region P free of agglomerates of interstitial-silicon-type point defects and agglomerates of vacancy-type point defects and/or a region R in which there is occurrence of ring-shaped oxidation induced stacking faults, and a step of performing rapid thermal annealing on the silicon wafer in a hydrogen atmosphere, an argon atmosphere or an atmosphere containing a mixed gas thereof.
